Q

What are carcinomas, sarcomas, lymphomas, and leukemias/myelomas?

A

Carcinoma: a malignant tumor originating in the epithelial tissue (skin, stomach, colon, breast, rectum)
Sarcoma: a malignant tumor originating in connective and mesodermal tissues (muscle, bone, fat)
Lymphoma: affecting the lymphatic system
Leukemia and myeloma: affecting the blood and blood forming organs (bone marrow)

Q

What is the purpose of cancer staging?

A

Stages describe the extent or severity of a person’s cancer.

Based on primary tumor (T), regional lymph node involvement (N) and metastasis (M).

Q

Describe the 5 stages of cancer.

A

Stage 0 = cancer in situ
Stage 1 = tumor is localized, equal to or less than 2 cm; has not spread to lymph nodes
Stage 2 = tumor is locally advanced; 2 cm to 5 cm with or without lymph node involvement
Stage 3 = tumor is locally more advanced; spread to lymph nodes; cancer is designated stage II or III depending on specific type of cancer
Stage 4 = the tumor has metastasized, or spread to other organs throughout the body

Q

Describe the 4 grades of cancer cells.

A 
Grade I (low-grade) = caner cells resemble normal cells (well differentiated) and are slow growing 
Grade II (intermediate grade) = cancer cells look more abnormal (moderately differentiated) and are slightly faster growing 
Grade III (high-grade) = cancer cells are abnormal (poorly differentiated); grow or spread more aggressively 
Grade IV (high-grade) = cancer cells are abnormal (undifferentiated)
